1. Environmental control strategy for pineapple flower plastic polytunnel greenhouse under the climate differences between the north and the south
Pineapple flowers (also known as ornamental pineapples) have high requirements for the growth environment, especially temperature, humidity and light conditions. Under different climate conditions in the north and south, the configuration of greenhouse equipment also needs to be adapted to local conditions. In warm and humid areas in the south, such as Guangdong and Fujian, greenhouse equipment mainly focuses on shading and cooling, humidity control, and uses plastic polytunnel greenhouse equipment such as external shading systems and wet curtain fans to reduce the impact of high temperature on pineapple flowers. In cold and dry areas in the north, such as Shandong and Liaoning, greenhouse equipment needs to focus on heat preservation and humidification. Double-layer strong plastic greenhouse or glass greenhouses are usually used, and equipped with heating systems and humidification equipment to ensure that pineapple flowers can safely overwinter.
2. Precise control of temperature and humidity: selection of heating and cooling equipment for pineapple flower plastic polytunnel greenhouse in different regions
The temperature range suitable for the growth of pineapple flowers is between 18℃-30℃. Temperatures below 15℃ or above 35℃ will affect their normal growth. Therefore, in different regions, the heating and cooling greenhouse equipment need to be precisely matched. In the cold northern regions, fuel heaters, water heating systems or floor heating systems are common heating strong plastic greenhouse equipment, especially water heating systems can provide more stable heat distribution and improve the overall energy efficiency of the strong plastic greenhouse. In the hot southern regions, greenhouse equipment needs to take cooling measures, such as installing wet curtain-fan systems, top ventilation skylights, etc., to promote air circulation and prevent excessive temperatures. In addition, for high humidity areas, air circulation fans and dehumidifiers can be used to prevent diseases.
3. Light management: How does the intelligent supplementary lighting system optimize the growth cycle of pineapple flowers?
Pineapple flowers have a high demand for light, but they cannot be under strong direct light for a long time. Therefore, light management is particularly critical in strong plastic greenhouse production in different regions. In the sunny south, summer greenhouse equipment needs to be equipped with sunshade nets or intelligent sunshade systems to prevent leaf burns. At the same time, adjustable LED supplementary lights can be used to provide appropriate supplementary light in rainy weather. In the north where the light is weak, especially in winter, LED plant fill lights or high-pressure sodium lamps are essential greenhouse equipment, which can increase the light time in the morning and evening and improve the photosynthesis efficiency of pineapple flowers. Some smart plastic polytunnel greenhouse is also equipped with light sensors to automatically adjust the switch of the fill light equipment according to the light intensity to ensure that pineapple flowers can obtain the most suitable light environment.
4. Irrigation and humidity control: water and fertilizer integration solutions under different climatic conditions
Pineapple flowers like a humid environment, but excessive water accumulation can easily lead to root rot, so reasonable irrigation and humidity control are essential for their healthy growth. In the humid areas of the south, plastic polytunnel greenhouse usually uses drip irrigation or micro-spraying systems, combined with drainage systems to prevent diseases caused by high humidity. In the dry areas of the north, the water and fertilizer integration system can more accurately adjust the water supply, while increasing the air humidity to prevent the leaves from drying up. In addition, the plastic polytunnel greenhouse uses of an intelligent water and fertilizer control system can automatically adjust the irrigation frequency and fertilizer application amount according to the growth cycle of pineapple flowers and the ambient humidity, improve the utilization rate of water and fertilizer, and reduce the cost of manual operation.
5. Intelligence and Automation: How Modern Pineapple Flower Greenhouse Equipment Improves Production Efficienciy
With the development of intelligent agriculture, modern pineapple flower plastic polytunnel greenhouse is increasingly using intelligent and automated greenhouse equipment to improve production efficiency. For example, the environmental monitoring system can monitor the temperature, humidity, light and carbon dioxide concentration in the strong plastic greenhouse in real time, and adjust the heating, cooling, ventilation and supplementary lighting equipment through the automatic control system. In addition, the intelligent sprinkler system can automatically adjust the irrigation frequency according to the soil moisture to avoid water waste or over-irrigation. In some high-end intelligent strong plastic greenhouse, a mobile plant transportation system is also equipped to make the management of pineapple flowers more convenient, improve production efficiency and reduce labor costs. In the future, with the continuous development of intelligent agricultural technology, pineapple flower greenhouses in different regions will be more efficient, energy-saving, and achieve precision production.
In summary, the equipment configuration of pineapple flower strong plastic greenhouse should be reasonably adjusted according to the climatic characteristics of different regions. Greenhouse equipment in the southern region needs to focus on cooling, shading and humidity control, while greenhouse equipment in the northern region needs to strengthen insulation, supplementary lighting and humidification measures. At the same time, the application of intelligent strong plastic greenhouse equipment can further optimize the greenhouse environment, improve production efficiency, and make the cultivation of pineapple flowers more scientific and efficient.
